Radon Mitigation Requirements in Pennsylvania

When receiving a quote for installation of a radon correction system, you need to be aware of the following requirements of PA Department of Environmental Protection:

1. The contractor shall conduct a thorough visual inspection which should be preformed prior to submission of the bid proposal to the client. The inspection is intended to identify any specific building characteristics or configurations (e.g. large cracks in slabs, exposed earth in crawl spaces, or open sump pits).

2. Sump pits that permit entry of soil-gas or that would allow conditioned air to be drawn into a sub slab depressurization system shall be covered and sealed. The sump cover shall have a radon-resistant drain if there is no other available floor drain.

3. Openings around radon vent pipe penetrations of the slab, the foundation walls, and the crawl space soil-gas retarder membrane shall be cleaned, prepared, and sealed in a permanent, airtight manner using compatible caulks or other sealant materials.

4. Openings, perimeter channel drains, or cracks that exist where the slab meets the foundation wall (floor-wall joint), shall be sealed with urethane caulk or equivalent material. Other openings or cracks in slabs or at expansion or control joints shall also be sealed.

5. Drain Installation requirement: floor drains and condensation drains that discharge directly into the soil beneath the slab, shall have a radon resistant drain installed.

6. The installer shall be certified by the Department of Environmental Protection.
